Description

Hewlett-Packard's AT-42070 is a general purpose NPN bipolar transistor that offers excellent high frequency performance. The AT-42070 is housed in a hermetic, high reliability gold-ceramic 70 mil microstrip package. The 4 micron emitter-to-emitter pitch enables this transistor to be used in many different functions. The 20 emitter inger interdigitated geometry yields a medium sized transistor with impedances that are easy to match for low noise and medium power applications.AT-42070 is designed for use in low noise, wideband amplifier, mixer and oscillator applications in the VHF, UHF, and microwave frequencies. An optimum noise match near 50 W up to 1 GHz, makes this device easy to use as a low noise amplifier.

The AT-42070 bipolar transistor is fabricated using Hewlett-Packard's 10 GHz f_T Self-Aligned-Transistor (SAT) process. The die is nitride passivated for surface protection. Excellent device uniformity, performance and reliability of AT-42070 are produced by the use of ionimplantation, self-alignment techniques, and gold metalization in the fabrication of this device.
